Architecture of Integrated Information Systems

Framework concept to describe enterprises

and application system development

Focused on business processes

112/04/21 IEEM, NTHU 3

Enterprise Process Modeling Concept

• The concept creates a guideline for developing, optimizing and implementing integrated application systems. Meantime, it shows business administration specialists how to view, analyze, document and implement information systems.

112/04/21 IEEM, NTHU 4

Why an Enterprise need a Framework for Integrated Information Systems

• Business software solutions comprise modules for accounting, purchasing, sales, finance, production planning, etc (with a high degree of complexity). Many corporate and external business partners are involved in the implementation of Information Systems. This becomes apparent in light of seamlessly integrated data processing, where data is shared by multiple applications.

• For example -- CIM in manufacturing companies, IS-supported merchandise management systems for retailers, electronic banking in financial institutions, IS-oriented concepts implemented in enterprises.

• 4M Modules – Money (Accounting, Finance, ..); Man (HR); Manufacturing (Procurement, Production, …); Marketing (Sales, Distribution, …)

Key Functionality

• Offers a framework (architecture) to completely describe standard software solutions (SSS).

• Integrates the most suitable methods for modeling information systems (IS) into the architecture, develops methods for describing business processes.

• Provides reference models as tools for the administration of application know-how, for modeling and analyzing system requirements.

112/04/21 IEEM, NTHU 9

Key Functionality (cont.)

• Industry-specific reference model for specific business processes (order management process, procurement process, customer service process, etc)

• For example, SAP (for electronic industry) procurement process reference model.

• Leveraging SSS, the business engineering tool(s) provide architectures for managing business processes. Using workflow systems, it is loosely linked with software “building blocks” (business objects). modules

112/04/21 IEEM, NTHU 10

Key Functionality (cont.)• You’re involved in procurement process. You will

have a “procurement” workflow management system that you need to comply with.

• For example, in your flow, you need to take care of 3 procurement approval tasks.

• Provides the framework for describing the assembly of software components (resulting in business IS) which are ideal for configuring workflow systems, generating screens and determining parameters for applications.

Basic Business Process ModelThe Initial Business Process Model

• Responsible entities and their relationship: organization, interaction

• Function flow: function, organization, function flow and organization flow

• Output flow

• Information flow: information services objects and other information objects

• Consolidated business process model
